The top-control layout contrasts Canon's minimalist style featuring a mode dial and minimal buttons, with Panasonic’s additional dedicated controls for exposure compensation and video functions. Both cameras lack illuminated controls or customizable buttons, limiting quick access in dim environments - a drawback for advanced users.

Sensor Technology and Image Quality

At the heart of any camera is the sensor, and despite an identical nominal size of 1/2.3" (6.17 x 4.55 mm), the two cameras use different sensor models that affect image fidelity and processing potential.

• Canon SX740 HS:

  • 20.3-megapixel backside-illuminated CMOS sensor
  • DIGIC 8 image processor enhances noise control and speed
  • No RAW support; outputs JPEG-only files
  • Sensitivity range ISO 100–3200
  • Optical low-pass (anti-alias) filter present
  • Sensor area approximately 28.07 mm²
  • Lack of RAW limits flexibility in post-processing, a significant consideration for enthusiasts.

• Panasonic ZS40:

  • 18-megapixel standard CMOS sensor (non-BSI)
  • Earlier Venus Engine processor, less advanced noise reduction
  • Supports RAW file capture, allowing broader editing latitude
  • ISO 100–3200 with boosted capability to ISO 6400
  • Optical low-pass filter present
